After installing the Sinister Diesel EGR Cooler, a new stock turbo, new EGR valve, and new #7 and #8 injectors, I am still getting the P0401 code. Each of those items needed to be replaced, by the way.
The motor runs fine; it just continues to throw the code. It has been to the dealer, and they can't figure it out. Is there a diagnostic procedure I can follow to hunt this elusive problem down?
I just picked up a 2011 Ford F350 about 8 months ago. I have had troubles with the check engine light coming and going. Now it's been on for good with loss of power. I have had the codes read and they came up as the p0401 and a code about the def heater. I can not remember that code off the top of my head. After some searching I have found a video about the def heater but nothing about the Egr cooler/valve. Is there anything out there about how to clean and remove the the cooler as I will be needing to do repairs myself as the truck has no warranty.
View 10 RepliesSo I'm about to do the oil and EGR coolers on my 6.0. At one point, or currently, my EGR cooler was leaking, so I've got that gooey residue in the intake, at least around the EGR valve. No dry carbon residue. I wondering what is the best way to clean the intake out, if at all. I have to assume there's some clogging in there, especially since I've had the P0401 code for a while. I just wanted to get this done right once, so I'm not coming back to it again any time soon....
View 5 Replies2012 F350 with 52,XXX miles and the P0401 keeps coming back with no degree of consistency, could be an hour later could be a week before it pops back up. just in th epast 4 days i have replaced the air filter (FOMOCO) and still same thing. there is no change in performance, just dont have that warm and fuzzy feeling since im about to head out to Colorado for 10 days with 5000 lbs of toys in tow.
btw, P0401 SAYS INSUFFICIENT PRESSURE FOR EGR
PURE STOCK, NO TUNING
My 2011 has 62k miles and has been throwing P0401 codes, which results in losing power. I assume the EGR cooler is clogged. So I went to the dealership to see if it's covered, and was told there's no warranty coverage.
I would rather blockoff the EGR cooler than repair it. I would also like the extra performance from a tuner like the MiniMaxx. I do prefer the stock exhaust and not real excited about the drone/smell that comes with deleted DPF.
Will I have issues if it's tuned with the EGR blocked off, and stock exhaust? Or am I better off doing a full delete at this point?
Near the end of a 5 hour drive on Christmas day my check engine light came on. I read the code: P0401. I got it into the dealer this week and was told it was a blocked EGR cooler. The truck has 66k miles. Lucky for me, I have the extended warranty! They replaced a "tube assembly". I sure hope this is not something that is going to repeat. I would hate to pay for this repair in the future. They had the truck 2 days. Is this a common problem or am I just "lucky"?
View 8 RepliesThe truck in question is a 2004 6.0L Excursion, stock original turbo, no tunes, and EGR cooler delete done 1 year ago. Scanned for codes and none were found except for EGR insufficient flow P0401 code which is due to the EGR cooler delete.
Upon startup (no issues there) the VGT reads 67-70, now once the truck goes to high idle to warm up (1150 or so RPM) the VGT slowing climbs to 85 and stays there. If I blimp the throttle or step on the brake it goes back to 67-70 at normal idle. This has been happening for a few months now on a regular basis. I have checked the MAP, BARO, and EBP readings at KOEO and they are all within 0.6 of each other (14.4-15.0). The EBP tube was checked and cleaned (no buildup present)..
2005 PSD Ex. 4x4.
Drove it a few nights ago and it felt really gutless. Next morning, no start. Well, it tried, but it sounded like it was run out of fuel (had half a tank)and I turned it off. Changed both fuel filters, key on / key off to purge system about 2 dozen times. Still no start.
I have all eight injectors with "injector Circuit Low" code, a P0401 - Exhaust Gas ReCir Flow Insufficient Detected, and P0672 - Glow Plug #2 (which it has had for a few months).
I thought with all of the injectors, it might be the FICM, checked the FICM voltage with Torque during a start and it showed 47V the whole time.
Harness? I did not think running with the glow plug error would be a big deal especially during the summer in So Cal.
Getting DTC P0401 on my 2011 with 92K miles. First time I got the CEL, we were on vacation, so I read the code, took a screen shot, then cleared it. Called my normal dealer, setup an appt, verified that they thought the truck was safe to drive. Coming home from vacation, I was pulling the TT in my sig, and noticed significant loss of power on hills that I have pulled many times before that I couldnt even hold 55 on now. Transmission dropped into 4th a couple times, on hills that it would sometimes stay in 6th, or at most drop to 5th.
CEL stayed off for a week , and came back on again. The funny thing is that after a day or 2, the CEL went back out on its own. I read the codes the P0401 is still there as a stored code(I did not clear this time). Around town the truck drives fine, the only thing I noticed was the decrease in power when towing. Truck is at the dealer now. TECH "isn't convinced" yet that there is a problem. He is not finished diagnosing yet, and I am sure that he has specific tests to run, but I am starting to fear that I will be getting the call to come get my truck.
I have 2013 f350 crew lariat 4x4 6.7 5000 miles . Cel coming on about 300 miles apart , 4th time now same code p054f ,dealer ship has no answers. Thayer say ford is investigating it ?? I don't about that but it is a real pain bringing it in.
View 1 RepliesI own a 2003 Ford F-450 Superduty Chassis w/Utility Body. Owned it for the last 2-1/2 years . So far, the only things needing replacement were an Alternator, FICM, and routine oil and transmission fluid as well as filters.
This past week the truck started lurching while in traffic. I brought it back to the shop and put the scanner on it, and found codes for #1,#3,#5 injectors imbalance and no circuit to the fan motor. Did some research and found low oil and/or dirty oil could affect the injectors, I changed the oil and all filters also removed the EGR and cleaned it too.
I started the truck ran it, stopped, and restarted and let it run for a few. I cleared the codes and did another test. The only code that came up was the Cooling fan P0528 again. I let the truck run. All of a sudden the truck revved up and I could hear the turbo kick in and the engine seemed to take a life of it's own. I did another round with the scanned and found codes for Cruise Control popping up P0565 through p0569 and the p0528 again along with a p1000.
My truck is not equipped with cruise control, but apparently that is what might be making the engine surge. What do I do? What this might be???
Truck started running rough on way home the other day. First gave me P0404 code and would get black smoke along with whitish smoke coming from the tail pipe. I haven't been able to notice or track an amount of coolant loss yet.
Swapped EGR valve this morning and now noticed this once she kicked into high idle (still warming up). About to hook up the IDS, hoping I this is not head gasket .

Truck has been running very well while in the warmer North Carolina climate pulling trailers with no limp mode or wrench light. However, when daughter started the truck this morning, SGII showed one DTC and when she pulled it up it was P0675. OK, glow plug num 5 maybe or the module. No issues starting or rough cold idle. I told her to clear the code and we'll see if comes back.
She did ask if it is something she should have it repaired before the trip back to Vermont. So I thought I'd ping the group here since reading posts, they seem to be fairly easy to replace (and assuming it isn't a chafed wire) and I could probably save her some $. Just want to make sure there isn't any chance of real engine damage.
My truck threw a CEL after the first start today. The CTS reports it twice. I noticed it about two minutes after start.
P02E1 - Diesel Intake Air Flow Control Performance
The air box gauge is green and it doesn't reset when I push it so that appears to be fine.
The one thing I can easily notice is the sound of the turbo. Typically when I stop and park, the turbo spools up, then down, then spools again and gives a sigh of relief and it's then silent. It's not doing that currently.
Now, I can hear it constantly when parked and it spools down after I turn off the engine, even two minutes later. That is not normal for my truck when I wait for the above to finish its routine. When I start the truck, the turbo immediately spools to where I can hear it which is also not normal, as if it's building 0.5 psi. I realize that's funny to say on a turbo diesel but I know the sounds of my truck. The EGT's are fine, EOT, ECT, TFT are fine and I can build boost when driving without issue. I took the drive to work easy this morning so the highest I noticed was 10 psi.
I restarted the truck after a 20 minute drive to the office and it didn't clear the CEL. The CTS squawked four times when it woke up the second time but it didn't show me which PID it was upset about.
I'm thinking this has nothing to do with the CAI and this is something downstream of there. EGR related? I haven't opened the air box yet, at work and in dress clothes so that'll need to wait. My past four or five regenerations all started between 1.94 and 1.97 soot gpl. That is also not normal and is something I have been keeping my eyes on. Currently the DPF is at 2.10 so it has made it further. Normal behavior (post emissions flash) is above 2.54 soot gpl for an AR.
It happened to me. I was 2 hours into my trip and towing the camper when I got the reduced power CEL. I have 28,000 miles on my truck and always tow in "tow/haul" mode with the exhaust brake on. I was lucky in that I has on a limited access highway and just happened to be approaching an exit to a fuel station with big rig access. I limped in there at about 20MPH checked the code with my Forscan lite and found the P259F code. I typed that into Google and found a thread on another Diesel forum! Some guys said it went away after 3 or 4 restarts. So, I tried a couple of restarts...no luck.
I was down to half a tank of fuel so I filled up and parked. As long as I was parked, I went into the camper and used the bathroom. When I got back in the truck, I thought about the WiFi scan adapter plugged into my OBDII connector and wondered if I should unplug it. I did and everything worked! So, I drove the next 4 hours in "tow/haul" mode, but I left the EB off. I also never plugged in the WiFi scan adapter because I didn't want to risk going into the reduced power mode again. Anyway, we made it home without incident. One of the reasons I traded my 2013 in on a 2015 was to get the engine improvements and the EB. I sure don't want to give up the EB. I'm going to take mine to the dealer, but after reading this post, I'm not expecting anything much.
Got this nugget this morning after dropping my daughter off at school. I also noticed a significant reduction in power. Had to get fuel so while pumping, I checked the code with my WiFi reader and Engine Link app.
Got the code number which came up with this: 6.7L ? MIL on with DTCs P208E P218F P204F ? 2011-2016 Ford F-Super Duty
I decided to clear the code and see if it would instantly return which it didn't. Power came back as soon as it was cleared too. Will see if it comes back. Looks like the code is saying there might be crystals on my DEF injector. I did have a regen last night right before I parked for the evening and then this showed showed up first thing this morning. Would a DEF injector nozzle be covered under the emissions warranty if it comes back?
Long story behind it but finally got my scanner working right and checked the suggested systems for p2290.
IPR was 77+ on start up dropped to around 31 at idle
FMP is in the 46.5 to 47.5 range
SYC was at 1 and occasionally at 1.5
ICP was at 550-650 during startup and quickly ramped up to 1150 then settled into around 850 at idle.
The only thing that I'm not sure of is the IPR being 31 at idle, is that what it should be. The others I think are within normal operating parameters.
The truck starts but has no power. Can barely go up a slight hill on my street. Seems like it's going to be fine but as soon as I apply a little gas it just falls off.
Local Volunteer Ambulance company has '09 -6.0 with very low power until warms up. Shows code P0234. FICM tests out 47.5- 48 volts.
Doing searce it looks like we have to pull turbo. Vehicle has 54K miles and never had EGR delete.
I just pulled over when my truck flashed reduced power. Pulled code and it came up poo88. What to expect?
View 3 RepliesSo I just went on a vacation pulling my horse trailer (first time leaving the state with this truck) and at about 5 hrs into the trip I had a message Reduced Engine Power and went from 70 on the interstate to 10 miles an hour and slowing rather quickly. I ended up shutting it off and restarting and it came back just like normal. I found the nearest ford dealer and they put the computer on it and it showed absolutely nothing, no codes and nothing wrong. The mechanic reset some things and we went on our way.
Then I ended up getting a check engine light saturday. I found someone to read the code and it came up with P164A which is an O2 sensor, he was able to clear it and I put on probably 50 miles today and no check engine light. I have about a 10 hour drive back home. Still debating if I take it to ford near here if they will do anything now that it doesn't show a light?? I hate to chance getting broke down on the highway with a truck that will basically shut down like that?? It just doesn't make sense to me.
Drove the truck to the store tonight about 5 minutes away and everything seemed fine. Went to leave the parking lot and noticed the check engine light was on. Pulled out my tablet, dongle and fired up Torque Pro. Retrieved error code P0170. Truck has a little over 12,700 miles and is complete stock. I ran a search and didn't come up with much info on this code other than what Just Stroken posted in another post.
